Update--Thursday 9 PM 3-10-22:

Winter storm watches include Wyoming, Livingston counties

UPDATE, 4 p.m.: The National Weather Service has issued a winter storm watch that will include Wyoming County. The watch begins 7 p.m. Friday and will be in effect through Saturday afternoon.

Heavy snow is possible, with total snow accumulations in excess of 7 inches possible. The greatest snowfall amounts are forecast across the higher terrain of the Chautauqua Ridge and Boston Hills. Winds could gust as high as 40 mph.

The advisory also includes Chautauqua Cattaraugus, and southern Erie counties. Travel could be very difficult. Areas of blowing snow could significantly reduce visibility, the Weather Service said.

Temperatures will fall through the 20s during the day Saturday leading to wind chill values falling into the single digits to near zero, the Weather Service said.

A winter storm watch will also begin Friday -- and continue until 1 a.m. Sunday -- for Livingston County.

No advisories have been issued for Genesee or Orleans counties, though the Weather Service said the potential exists for widespread accumulating snow Friday night through the first half of Saturday with at least several inches of snow possible. 

The Weather Service forecasts 2 to 4 inches of snow Friday night for Genesee and Orleans counties. On Saturday, the forecast is for an additional 1 to 3 inches in Genesee County, and around an inch in Orleans County.

Original story, 8 a.m.:

Winter is not through with us yet. The National Weather Service was issued a winter storm watch that includes Livingston County that will be in effect from Friday evening through late Saturday night.

Heavy snow is possible, with total snow accumulations in excess of 7 inches possible, according to the Weather Service. The snow could be accompanied by winds gusting as high as 45 mph. 

The watch also includes Ontario, Allegany, Wayne, northern Cayuga, Oswego, Jefferson and Lewis counties. Travel could be very difficult to impossible. Areas of blowing snow could significantly reduce visibility. The hazardous conditions could affect the evening commute. 

While no watches have yet been issued for Genesee, Wyoming or Orleans counties snow is expected to be widespread across upstate New York. 

The Weather Service, in an hazardous weather outlook that included Genesee, Orleans and Wyoming counties said the potential exists for widespread accumulating snow Friday night through the first half of Saturday with at least several inches of snow possible. 

The outlook also includes Monroe, Niagara, northern and southern Erie counties, Chautauqua and Cattaraugus counties. 

 High pressure stretching from the Rockies across the northern tier of the country will generally be in control of the region’s weather through at least Friday morning, the Weather Service said in a forecast discussion this morning. 

Conditions will then deteriorate as a pair of storm systems will take aim on our region for the weekend. From this vantage point, “it appears highly likely that at LEAST several inches of snow will fall across all of western and north central New York,” the Weather Service said. 

The highest snow amounts -- in excess of 7 inches -- are expected across the Finger Lakes eastward through the area east of Lake Ontario, the Weather Service said in its forecast discussion. 

As the low pulls east, wrap around moisture and the cold air will support lake enhancement Saturday afternoon and pure lake effect snow Saturday night, thus adding an additional few inches to the areas east-southeast of both lakes, the discussion said. 

Winds will become quite gusty late Saturday and Saturday night as the surface low pulls away from the region which may bring additional impacts to the region (i.e. blowing snow), the Weather Service said. 

A winter storm watch will also be in effect from Friday evening through late Saturday night for Steuben County. Total snow accumulations of 7 to 12 inches possible. Winds could gust as high as 40 mph, the Weather Service said. 

The watch also includes Yates, Seneca, northern and southern Oneida, southern Cayuga, Onondaga, Schuyler, Tompkins, Madison and Cortland counties.
